将 ProGuard 与 Android 配合使用

我在处理ProGuard和Android时遇到问题。

我在网上搜索了几个小时，发现了多种方法来混淆Android应用程序。现在，我正在尝试一个看起来最简单的方法，所以：

• 我在项目的根目录中创建了一个文件config.cfg
• 我添加了我的proguard.config=config.cfgproject.properties
• 我使用 Eclipse 导出向导导出并签署.apk文件

我收到一条消息，说和在控制台中：Proguard returned with error code 1. See console

Proguard returned with error code 1. See console
Note: there were 3847 duplicate class definitions.

      You should check if you need to specify additional program jars.
Warning: there were 4 unresolved references to classes or interfaces.
         You may need to specify additional library jars (using '-libraryjars').
Error: Please correct the above warnings first.

即使我使用官方Proguard网站提供的配置，或者默认的配置，我也有错误。
这是我的自定义配置（myProject/config.cfg）：

-injars      bin/classes
-injars      libs
-libraryjars "C:\Program Files\Android\android-sdk\platforms\android-13\android.jar"

-dontskipnonpubliclibraryclasses
-optimizationpasses 5
-printmapping map.txt
-flattenpackagehierarchy
-dontpreverify
-repackageclasses ''
-allowaccessmodification
-optimizations !code/simplification/arithmetic
-keepattributes *Annotation*

-keep public class * extends android.app.Application
-keep public class * extends android.app.Activity
-keep public class * extends android.app.PreferenceActivity
-keep public class * extends android.view.View
-keep public class * extends android.widget.BaseAdapter
-keep public class * implements android.view.View.OnTouchListener

-keep public class * extends android.view.View {
    public <init>(android.content.Context);
    public <init>(android.content.Context, android.util.AttributeSet);
    public <init>(android.content.Context, android.util.AttributeSet, int);
    public void set*(...);
}

-keepclasseswithmembers class * {
    public <init>(android.content.Context, android.util.AttributeSet);
}

-keepclasseswithmembers class * {
    public <init>(android.content.Context, android.util.AttributeSet, int);
}

-keepclassmembers class * extends android.content.Context {
   public void *(android.view.View);
   public void *(android.view.MenuItem);
}

-keepclassmembers class * implements android.os.Parcelable {
    static android.os.Parcelable$Creator CREATOR;
}

-keepclassmembers class **.R$* {
    public static <fields>;
}

我无法让它工作...任何想法将不胜感激！
